Interesting observation, but I would contend that Alco did just fine while GE was designing the electrics. Alco was the first to build a Diesel-electric in 1929. Later the RS series defined the market for about three years until EMD responded with the GPs. When GE went their own way is what doomed Alco, or maybe that is what you meant by the rise of GE. I would also contend that the only reason GE stayed in business through the 70's was several of the railroads "threw them a bone" so to speak just to keep them in business so EMD would have at least one competitor.
